Support-k8s-1.26 (#693)

## What
allow installation on k8s `1.26.x` (previously we allowed only up to
`1.25.x`)
no other code changes required to support `1.26`

## Why
EKS has 1.26 available, and i'm sure other cloud providers as well

## Notes
improved k8s version check to use semver semantics for `1.21-0 - 1.26-0`
